I put up a 30'x40' Mueller Steel Building from a bolt together kit 6 yrs ago. Fully insulated, 2 10'x10' roll up doors, 1 walk thru door, 3 windows, 2' overhang all around, and gutters. The building price minus the slab was about $9500. The only special equipment was a neighbor's large Farmall with a hay spike on the FEL that we used to lift the trusses in place. Then it was mainly cordless drills to put in LOTS of self tapping screws, circular saw with metal cutting blade, tall ladders, etc. Had help putting up the trusses and putting up the roof panels. Everything else I did by myself. Took about 6 wks, but that was only working weekends and maybe 3 evenings a week since that land is 30 miles from my house. Would have gone a lot faster with at least one helper.s

Strontium steel is created by soaking a mild steel in strontium chromate, which has a pH of about 4 or 5, roughly the equivalent of acid rain. Chromate affects the cathodic reaction, with reduction of Cr6+ to Cr3+, and the surface film was composed of magnetite and hydrated chromium hydroxide. The Strontium is a radioactive isotope. The acid bath permeates the mild steel causing it to become mildly radioactive. Simular to oil imprengation of brass and other metals. Strontium Steel has a very high value of inhibition. However due to it's radioactive properties it is not a commonly used or manufactured material. As for where to actually obtain Strontium steel dowels. I have no idea i would speculate that you would have to purchase the raw stock and have it machined into a dowel for you.s

Yes, stainless steel is stainless all the way through. All metals are uniform in composition throughout the piece. However, many metal items are plated to give a different finish from the base metal or to provide protection. An example is galvanized ductwork. The duct is made of steel, but a coating of zinc is plated onto it for corrosion resistance. Likewise, some items are made of steel or brass, but are chrome plated to present a bright, shiny appearance.s

This Site Might Help You. RE: Is a knife with damascus steel better than one with regular steel? or what about high carbon? What would be a better knife one with damascus steel or one without? Why is damascus steel so special other than the look? And why do some people say high carbon steel is better than regular? mainly though I want to know about the damascus. Thanks, max points to best answer.s

To obtain the outer diameter of the steel coil is calculated according to the density of 7850, according to the density, in general, hot-rolled is 0. 96~0, 98, cold rolled, according to 0. 98~0. Ninety-nines

Material selection is a complex area. Iron and steel are very good materials in terms of their strength, stiffness and hardness (especially when compared to their density to give specific strength/stiffness. They are also relatively cheap and the economics of material selection is often the over-riding criteria. Each individual substitution has to be considered on the merits of what the component has to do and the environment in which it operates and often to replace steel with, say, aluminium, might not be appropriate or might require a redesign of the component to accomodate the lower strength and stiffness. Take one of your examples of a dishwasher; To replace the (cheap and thin) steel outer casing with aluminium would require thicker sheet to achieve the same stiffness. To replace the stainless steel inner you would need a corrosion resistant material (which rules out aluminium) which can be easily fabricated to shape. Nickel alloys would be harder to process and very expensive, but you might be able to use a bronze alloy. If you have time look in the library for a book on materials selection by Ashby - one of the best texts on the subject.s
